Sorry, but I can't.  However, the OS is strongly oriented towards security 
paranoia.  As long as the proper OS calls are used to delete files and release 
memory, you can assume that they are unrecoverable, with all the stuff a 
forensic expert would hate.  The same is true of any caching done at OS level 
or below (e.g. device drivers, storage which automatically manages sector 
usage, etc.).

You got it.  But the platform (OS and hardware) is specially designed for this. 
 As you suspected I'm concerned only at the level of filespace which is still 
in use.
